Let's divide 77200350 by 453
We're looking to find how many times 453 goes into 77200350.

Advancing to step 1:
453 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 453

On to step 2:
If we divide 77 by 453, we get 0 and a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Append the next digit (2) from the dividend to 77 and continue with: 772 / 453

Step 3:
The number 453 fits into 772 1 times, leaving a remainder of 319.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 319 after subtracting 453 from 772.
Bring next digit (0) of the dividend behind the 319 and repeat the process: 3190 / 453

Going ahead to step 4:
453 goes into 3190 7 times with a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtract 3171 from 3190 to get 19.
Include the next digit (0) from the dividend after 19, then repeat: 190 / 453

Moving on to step 5:
453 can be fit into 190 0 times, resulting in a remainder of 190.
Write down 0 as next digit of the result. 
Result so far: 170.0
If we subtract 0 from 190, we get 190.
Take the next digit (3) from the dividend and append it to 190, then repeat: 1903 / 453

Step 6:
453 can be fit into 1903 4 times, resulting in a remainder of 91.
Put 4 as the next digit of the answer. 
Result so far: 1704.0
Subtracting 1812 from 1903 leaves us with 91.
Take the next digit (5) from the dividend and append it to 91, then repeat: 915 / 453

Moving on to step 7:
When dividing 915 by 453, we get 2 with a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 17042.0
Subtract 906 from 915 to get 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 453

Going ahead to step 8:
When dividing 90 by 453, we get 0 with a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 170420.0
Subtract 0 from 90 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 9:
900 divided by 453 is 1 with a remainder of 447.
The number 1 becomes the next digit in our result. 
Result so far: 170420.1
Subtract 453 from 900 to get 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

Advancing to step 10:
4470 divided by 453 is 9 with a remainder of 393.
Write down 9 as next digit of the result. 
Result so far: 170420.19
If we subtract 4077 from 4470, we get 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Going ahead to step 11:
3930 divided by 453 is 8 with a remainder of 306.
The number 8 becomes the next digit in our result. 
Result so far: 170420.198
Subtracting 3624 from 3930 leaves us with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Going ahead to step 12:
453 can be fit into 3060 6 times, resulting in a remainder of 342.
The next digit of our result is 6. 
Result so far: 170420.1986
Subtracting 2718 from 3060 leaves us with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Going ahead to step 13:
453 goes into 3420 7 times with a remainder of 249.
Write down 7 as next digit of the result. 
Result so far: 170420.19867
Deduct 3171 from 3420 and we're left with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Step 14:
453 can be fit into 2490 5 times, resulting in a remainder of 225.
The number 5 becomes the next digit in our result. 
Result so far: 170420.198675
Subtracting 2265 from 2490 leaves us with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Step 15:
When dividing 2250 by 453, we get 4 with a remainder of 438.
Use 4 as the next digit of our solution. 
Result so far: 170420.1986754
The remainder is 438 after subtracting 1812 from 2250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Moving on to step 16:
453 goes into 4380 9 times with a remainder of 303.
Put 9 as the next digit of the answer. 
Result so far: 170420.19867549
Deduct 4077 from 4380 and we're left with 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

The final result is 170420.19867549 with a remainder of 3.03e-07.
